Abstract

PURPOSE: To improve amenity by controlling a flow control valve provided between an oil separator and a suction pipe of a compressor to a larger flow rate, an expansion valve to the maximum flow rate and the capacity of the compressor to an increase during the defrosting operation in the return of a refrigerant and refrigerating machine oil and in the control of the defrosting operation. CONSTITUTION: When detecting frost on an outdoor side heat exchanger 7, a defrosting operation control means increases the capacity of a compressor 12 to open the travel of an electromagnetic expansion valve 6 to the full capacity. At the same time, the travel of a flow control valve 13 is increased to allow bypassing in flow rate between high and low pressures of the compressor 12. An outdoor side blower 11 is stopped to reduce the amount of air of a room heat exchanger 10. This prevents the destruction of the compressor 12 as caused by the compression of a liquid while allowing the continuation of heating as intact during the defrosting thereby improving amenity.
